Nodejs:Messenger在发送广播消息请求时显示错误数据错误



我目前正在尝试自动化向Facebook发送广播消息的过程，以便我可以从API调用中触发它。

接收并处理对我的 API 的 Http 请求，但当进程开始将消息发送到message_creatives终结点时，它会返回以下错误：

{ Error: Request failed with status code 400

注意：出于安全原因，它说ACCESS_TOKEN的地方是我在发布之前故意编辑的，因此该部分工作正常。

我完成这项工作的代码是这样的：

const templates = require('./templates')
const dialogsContent = require('../dialogs-content').dialogsContent
const axios = require('axios')
class broadcastSender {
static formatMessage (message) {
return templates.format(message)
}
static async getCreativeId (message) {
// -- The format of the message from the dialog is in a generic format
// -- We need to format it to the Facebook format
const formattedMessage = this.formatMessage(message)
// -- Execute the first step to send a single Broadcast Message
// -- Get that message's ID from Facebook
await axios.request({
headers: { 'Content-Type': 'application/json' },
url: `${process.env.FB_BASE_URL}/${process.env.FB_VERSION}/me/message_creatives?access_token=${process.env.FB_ACCESS_TOKEN}`,
method: 'post',
data: formattedMessage,
})
.then(data => {
return data.message_creative_id
})
.catch(error => {
console.log(error)
})
}
static async prepareCreativeIdsArray (dialogName) {
// -- The Dialog is an array of messages
// -- We get the Dialog and assign it to a messages array
const messagesArray = dialogsContent.messages[dialogName]
const IdsArray = []
// -- Fill the array with the Ids of the BroadCast Messages
for (const message of messagesArray) {
const messageIdFromFacebook = await this.getCreativeId(message)
if (!isNaN(parseInt(messageIdFromFacebook, 10))) {
IdsArray.push(messageIdFromFacebook)
}
}
return IdsArray
}
static async getCustomLabelId (label) {
const labelsIdsArray = (await axios.get(`${process.env.FB_BASE_URL}/${process.env.FB_VERSION}/me/custom_labels?fields=name&access_token=${process.env.FB_ACCESS_TOKEN}`)).data.data
for (const labelData of labelsIdsArray) {
if (labelData.name === label) {
return labelData.id
}
}
}
static async sendBroadcastMessage (dialogName, labelToExclude) {
const IdsArray = await this.prepareCreativeIdsArray(dialogName)
const customLabelId = await this.getCustomLabelId(labelToExclude)
console.log('IDS ARRAY %sn labelid %s', IdsArray, customLabelId)
for (const broadcastId of IdsArray) {
const creativeData = Object.assign({},
{
message_creative_id: broadcastId,
notification_type: 'REGULAR',
targeting: { labels: { operator: 'NOT', values: [{ customLabelId }] } },
})
// -- Send the message to facebook
await axios.request({
headers: { 'Content-Type': 'application/json' },
url: `${process.env.FB_BASE_URL}/${process.env.FB_VERSION}/me/broadcast_messages?access_token=${process.env.FB_ACCESS_TOKEN}`,
method: 'post',

})
.then(data => {

.catch(error => {
throw error
})
}
}
}
module.exports = broadcastSender

const isPersonalized = /{{first_name}}/i
if (isPersonalized.test(JSON.stringify(payload))) {
type = 'dynamic_text'
fallback_text = payload.replace(isPersonalized, 'buddy')
}
let preparedMessage

想要的行为向信使发送广播消息过程的第一步应该返回一个具有"message_creative_id"属性的对象。

我发现了错误，它是"消息"末尾缺少的"s"。 Facebook具有类似的格式来向用户发送回复，因此当将这种格式用于广播消息而不是"消息"具有称为"消息"的属性

时，出现了问题。
